Globally speaking, November was a warm month, at least for a November. GISTEMP, NOAAGlobalTemp and HadCRUT4 all have November as the warmest November on record nominally. Part of the warmth, at least the part that distinguishes it form 2014, say, is likely due to the El Nino that matured mid-year. There are various estimates of the effect that El Nino has on monthly temperatures (directly because the El Nino region is rather large and part of the surface and indirectly because El Nino warms other areas with some lag) but are around a tenth of a degree or so.

As usual, record global heat arises in an aggregate of warmer and colder areas. In November 2015, cooler areas of the world were the western US, western Greenland, Argentina, parts of central and eastern Eurasia, parts of the Southern Ocean, the Antarctic Peninsula. As cold as some of these places were, relative to what’s normal for the time of year, the list of warmer than average locations was much longer. Large areas of the tropics were either much warmer than average or record warm. This included large areas of the Indian Ocean, Central America and northern parts of South America. The eastern US (rounding out a record Autumn for the contig US as a whole), Europe, southern parts of Eurasia, large areas of Africa, Oceania, Australia were all much warmer than average.

A surprisingly large number of countries found that the November they had just lived through was the 3rd warmest on record. There is no word for this experience. The UK, France, Switzerland, Finland, Denmark and Australia all pegged November 2015 as 3rd warmest on record. On the 1st November a temperature of 22.4degC was recorded at Trawsgoed in the UK, the highest temperature ever recorded in the UK in November. Finland also saw a new record high November temperature when 14.3degC was recorded at Kemiönsaari. In France, the country-wide monthly average maximum temperature was the highest on record. Although Australia had its 3rd warmest November on record, the gap between 2015 and either 2009 or 2014 (the other two of the three warmest) was only around one one-hundredth of a degree. The Australian spring was the 2nd warmest on record overall. South Korea had its second warmest November on record.

Over Europe, November was generally much wetter than average across the North (UK, Denmark, western parts of Norway) and drier than average across the south (Iberian Peninsula, Italy, Turkey), a pattern that continued, somewhat shifted into December. Denmark had its second wettest November since at least 1874. An area of wetter than average conditions reached all the way across Eurasia from Europe to Japan (in some western areas on the Pacific side it was the dullest November on record since 1946), cutting through Kazakhstan, Mongolia, northern China, Korea (second wettest on record) on the way.

South eastern parts of China (with the exception of a small coastal strip) were wetter than average in November. Brazil was largely dry, except the south where there was an area of above average rainfall, which also encompassed Uruguay, Paraguay and parts of Argentina. This pattern (dry Brazil, wet to the south), which is typical of El Nino, continued into December. Heavy rain in Argentina led to flooding. Some stations reported their highest 24-hour and monthly totals for November. There was also flooding in Asuncion on the Paraguay river.

Parts of the eastern US were wetter than average. Arkansas and Missouri were record wet for the month. Parts of equatorial Africa were wetter than average, drier conditions were observed further south. Indonesia and western Pacific islands were largely drier than average though there were some areas which had above average rainfall. Heavy rain led to flooding in parts of Kenya. Heavy rain in November affected eastern areas of India, with significant flooding in Tamil Nadu with the city of Chennai badly affected. Further heavy rain in early December affected the city also.
